Most of the changes are just trivial are just trivial replacements of
fields from MpegEncContext with equivalent fields in H264Context.
Everything in h264* other than h264.c are those trivial changes.
The nontrivial parts are:
1) extracting a simplified version of the frame management code from
mpegvideo.c. We don't need last/next_picture anymore, since h264 uses
its own more complex system already and those were set only to appease
the mpegvideo parts.
2) some tables that need to be allocated/freed in appropriate places.
3) hwaccels -- mostly trivial replacements.
for dxva, the draw_horiz_band() call is moved from
ff_dxva2_common_end_frame() to per-codec end_frame() callbacks,
because it's now different for h264 and MpegEncContext-based
decoders.
4) svq3 -- it does not use h264 complex reference system, so I just
added some very simplistic frame management instead and dropped the
use of ff_h264_frame_start(). Because of this I also had to move some
initialization code to svq3.

Replace our incomplete w32threads implementation with x264's pthreads

FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture. Replace by an embedded AVFrame structure in struct Picture.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the

This eliminates all aliasing violation warnings in h264 code.
No measurable speed difference with gcc-4.4.3 on i7.

is closer at the top.
50-130 cpu cycles faster depending on which kind of direct MBs are meassured.

A little faster and needed for future optimizations.
This sadly leads to some code duplication (which i hope i can factor out
again after the optimizations on the direcr mv code are done)

as 16x16 (except ones changing interlacing relative to the colocated MB).
20 cycles slower during MV generation
175 cycles faster during MC
